8585740383 | Adaptation(s) | Inherited characteristic of an organism that enhances its survival and reproduction in specific environments. | 0 | |
8585740384 | Analogous | Having characteristics that are similar because of convergent evolution, not homology. | 1 | |
8585740385 | Artificial Selection | The selective breeding of domesticated plants and animals to encourage the occurrence of desirable traits. | 2 | |
8585740386 | Biogeography | The study of the past and present distribution of species. | 3 | |
8585740387 | Catastrophism | The principle that events in the past occurred suddenly and were caused by different mechanisms than those operating today. See uniformitarianism. | 4 | |
8585740388 | Continental Drift | The slow movement of the continental plates across Earth's surface. | 5 | |
8585740389 | Convergent Evolution | The evolution of similar features in independent evolutionary lineages. | 6 | |
8585740390 | Endemic | Referring to a species that is confined to a specific, relatively small geographic area. | 7 | |
8585740391 | Evolutionary Tree(s) | A branching diagram that reflects a hypothesis about evolutionary relationships among groups of organisms. | 8 | |
8585740392 | Fossil(s) | A preserved remnant or impression of an organism that lived in the past. | 9 | |
8585740393 | Homologous Structure(s) | Structures in different species that are similar because of common ancestry. | 10 | |
8585740394 | Homology | Similarity in characteristics resulting from a shared ancestry. | 11 | |
8585740395 | Marsupial | A mammal, such as a koala, kangaroo, or opossum, whose young complete their embryonic development inside a maternal pouch called the marsupium. | 12 | |
8585740396 | Natural Selection | A process in which organisms with certain inherited characteristics are more likely to survive and reproduce than are organisms with other characteristics. | 13 | |
8585740397 | Paleontology | The scientific study of fossils. | 14 | |
8585740398 | Pangaea | The supercontinent that formed near the end of the Paleozoic era, when plate movements brought all the landmasses of Earth together. | 15 | |
8585740399 | Stratum | A rock layer formed when new layers of sediment cover older ones and compress them. | 16 | |
8585740400 | Trait(s) | Any detectable variant in a genetic character. | 17 | |
8585740401 | Uniformitarianism | The principle stating that mechanisms of change are constant over time. See catastrophism. | 18 | |
8585740402 | Vestigial Structure | A structure of marginal, if any, importance to an organism. Vestigial structures are historical remnants of structures that had important functions in ancestors. | 19 |
